Part connection with metal nose ring 210 copper core or aluminium cable 200 so that formed one connection electrical equipment or power supply unit it is normal
Use connection cable.From unlike first embodiment, connecting cavity 110 is shown as cylinder.Shown in Fig. 5 is according to the disclosure
The schematic diagram of the electric connector 100 of two embodiments.Shown in Fig. 6 is electric connector according to disclosure second embodiment
Sectional view.As it can be seen in figures 5 and 6, second embodiment from unlike first embodiment, in low-melting-point metal connection member 140
Heeling-in has one, two or three metal derby 145.Shown in Fig. 5 is electric connector according to disclosure second embodiment
Sectional view.As it can be seen in figures 5 and 6, be used to be conductively connected the end of conductive core 130 in the low-melting-point metal connector 140
During end, one or more metal derbies 145 are arranged between the end of conductive core 130, then made by low-melting-point metal of casting
Its heeling-in is in low-melting-point metal connector 140.Or, directly when low-melting-point metal connector 140 is formed by one or many
The heeling-in of individual metal derby 145 wherein, then by the two ends hot-melt adhesive paste of low-melting-point metal connector 140 to conductive core 130
End.The fusing point of the metal derby 145 and density are all higher than the fusing point and density of the low-melting-point metal, therefore during heeling-in
When being melted with low-melting-point metal connector 140, the metal derby 145 is all in solid state.Its on second embodiment
His part, due to identical with first embodiment, therefore not in this repeated description.
When in use, all it is higher than the low melting point because the solidified inside of low-melting-point metal connector 140 has fusing point and density
The fusing point of metal and the metal derby 145 of density, therefore, the temperature of low-melting-point metal connector 140 be increased to its fusing point it
When above melting, the metal derby 145 relies on its gravity fall, while under driving the fusing low-melting-point metal acceleration of trickling downwards
Fall or trickle, so that the electrical connection of conductive core 130 described in fast shut-off.
Metal derby 145 in electric connector according to disclosure second embodiment can be spherical pieces.In same volume
In the case of, spherical watch area is minimum.Therefore, when low-melting-point metal connector 140 melts, its surface to metal ball 145
Power is minimum, and the frictional resistance of generation is also smaller, is more beneficial for the whereabouts of metal derby, is also more conducive to drive the low melting point gold of fusing
Category trickling downwards and whereabouts, so that the electrical connection between property cut conductive core 130.The metal derby 145 can also be other
Shape, such as rectangle or taper.If rectangle or taper, caused in heeling-in metal derby 145 surface area of metal derby 145 compared with
Small one side or pointed end, to be conducive to the whereabouts of metal derby.
Further, since heat transfer is present, and the regular hour is poor, in order that the low-melting-point metal part 140 that must be melted disconnects as early as possible
Electrical connection between conductive core 130, can arrange multiple metal derbies in low-melting-point metal part 140 along closure
145.So, when electrical equipment or power supply unit transmit the shortage of heat come disposably to melt all low-melting-point metal parts
When 140, a part of low-melting-point metal may be first melted from left side or right side, then in the low-melting-point metal that this is melted
One of metal derby 145 can first drive the part low-melting-point metal of fusing to fall, such that it is able to disconnect conductive core as soon as possible
Electrical connection between 130, and without when all of low-melting-point metal part 140 all melt can just disconnect conductive core 130 it
Between electrical connection.In this case, the quantity of the metal derby 145 is 2 or 3 pieces.The metal derby is usually metallic iron, gold
Category copper etc., can be other metals of other high density, high-melting-point and good conductivity.
Although being configured without the electric power of first embodiment in the electric connector 100 of the second embodiment shown in Fig. 4-6
The structure of compression spring 160 shown in connector 100, but one can also be entered in the electric connector 100 of second embodiment
Step installs compression spring 160 additional, to accelerate the whereabouts of low-melting-point metal, accelerates the electrical connection of the cut-out conductive core 130
Speed.
Although describing two kinds of electric connectors 100 above for the first and second embodiments, connect when using electric power
Connect device 100 connection cable may when in use can't horizontal positioned, and may right angle setting.Although this vertical mode
Placement will not cause the realization of the technical scheme of the disclosure, i.e. low-melting-point metal part 140 can still trickle after being melted down or under
(now, the side wall of the connecting cavity where the root of side conductive core 130 becomes to fall the root of the conductive core 130 of side
" bottom ") so as to cut off the electrical connection between conductive core 130, but because the presence of conductive core 130 can delay fusing
The downward trickling of low-melting-point metal part 140 or the speed of whereabouts.For the speed for improving trickling or fall, root is proposed
According to the electric connector 100 of disclosure 3rd embodiment.Shown in Fig. 7 is according to the electrically connected of third embodiment of the present disclosure
The schematic appearance of device 100.As the electric connector 100 shown by second embodiment, it is mainly connected by a cylinder
Connect chamber 110 to constitute, copper core or aluminium cable 200 of the connector connection that it passes through inside with metal nose ring 210, so as to be formed
One connection electrical equipment or power supply unit often use connection cable.From unlike second embodiment, connection cable is overall vertical
Arrangement.Shown in Fig. 8 be electric connector according to third embodiment of the present disclosure schematic diagram.Shown in Fig. 9 is according to this
The sectional view of the electric connector of disclosed 3rd embodiment.As shown in FIG. 8 and 9, low-melting-point metal connection member 140 vertically connects
Connect the exposed conductive core 130 from connecting cavity perforation insertion of both sides about 110.The shape of end 135 of the conductive core 130
Coning or pyramid.Thus, include electric connector 100 cable 200 be in vertical use state under, when due to
Electric equipment or power supply unit generate heat and cause the low-melting-point metal connection member 140 in connecting cavity 110 to be generated heat and melted more than fusing point
When, the low-melting-point metal of molten state the supporting for being subject to because the end 135 of conductive core 130 forms cone or pyramid
Area is small, and thus support force is also small, therefore is easier trickling downwards and falls such that it is able to accelerate to disconnect conductive core 130
Electrical connection.
It is pointed out that in order that obtaining the low-melting-point metal connection member in the connecting cavity 110 under this arrangement states
Quickly trickled downwards after 140 heatings or fallen, as shown in FIG. 8 and 9, between the tapered distal end of upper and lower conductive core 130
Heeling-in has metal ball 145 in low-melting-point metal connection member 140.Equally, the fusing point and density of the metal ball 145 are all higher than described
The fusing point and density of low-melting-point metal.Therefore, it is increased on its fusing point in the temperature of low-melting-point metal connector 140 and is melted
During change, the metal ball 145 keeps solid-state, and due to losing its holding after the fusing of low-melting-point metal connector 140, and make
For the area of the tapered distal end of the conductive core 130 of the strong point is minimum, it is thus in unstable state and relies on its gravity downward
The bottom of portion's conductive core 130 tumbles, so that drive the fusing low-melting-point metal of downward trickling to accelerate to fall or trickle, so that soon
